Abstract (en)
[origin: EP1503516A2] This invention is directed to a mobile communication system in which the downlink transmission power of a base station is controlled in accordance with a power control bit from a mobile communication terminal, a mobile communication terminal, a power control method, and a program. According to the invention, in order to reliably perform power control even during soft handover communication with a plurality of cells, a determination unit is provided which determines whether the downlink transmission power of a base station complies with the power control bit transmitted from the mobile communication terminal. <IMAGE>
